THE vertices of ABC are A(-2,2,B(6,2,and c(0,8). The perimeter of ABC is

1 answer:

4 0

Using the distance formula:

AB^2 = (-2-6)^2 = (2-2)^2
      = 64
    AB = 8 units
BC^2 = (6-0)^2 + (2-8)^2
      = 36 + 36
= 72
BC = 6 root 2
AC^2 = (-2-0)^2 + (2-8)^2
= 4 + 36
= 40
AC = 2 root 10

Perimeter = 8 + 6 root 2 + 2 root 10
   = 2 (4 + 3 root 2 + root 10) units

Which represents where f(x) = g(x)?

Alexxx [7]

Answer:

f(2) = 9(2) and f(0) = g(0)

Step-by-step explanation:

As in the expression f(x) = g(x), the values in parentheses need to be the same for both f( ) and g( ). That is only the case for the first answer choice.

Yasmine estimated the difference of 87.71 and 5.8 by rounding each number to the nearest whole. What was Yasmine's estimate, and

Alex73 [517]

Answer:

Yasmine estimated the difference to be 82. The actual difference is 81.91.

Step-by-step explanation:

The rounded whole number of 87.71 is 88 and the rounded whole number of 5.8 is 6.

So, the difference between the numbers 87.71 and 5.8 by rounding each number to the nearest whole numbers will be

(88 - 6) = 82.

The actual difference between the numbers 87.71 and 5.8 is (87.71 - 5.8) = 81.91.

Therefore, Yasmine estimated the difference to be 82. The actual difference is 81.91. (Answer)

In the data set below, what are the lower quartile, the median, and the upper quartile?

Studentka2010 [4]

The median, upper and lower quartiles of the data set are:

Lower Quartile = 46

Median = 49

Upper Quartile = 90

<h3>What is the Median?</h3>

The center value or middle value of a data set is the median.

<h3>What are the Upper and Lower Quartiles?</h3>

Upper quartile (Q3) is the center or middle data point of the second half of a data set.

Order the data set given as:

32, 46, 49, 49, 77, 90, 96

Lower Quartile = 32, (46), 49, 49, 77, 90, 96 = 46

Median = 32, 46, 49, (49,) 77, 90, 96 = 49

Upper Quartile = 32, 46, 49, 49, 77, (90,) 96 = 90
